"Don't sell, don't lose" isn't correct imo.
All it means is that you haven't realized a loss for accounting purposes, but in the meantime you've suffered an economic impairment as evidenced by the decline in personal net wealth.
I think we'd agree that someone with $1,000,000,000 in net worth is better off economically than someone else with $1,000 net worth plus $999,999,000 in Unrealized Losses.
One time I got myself into a hole. After a painful round of deliberation, I made a decision to bite the bullet, sell and put the remaining funds in tried-n-true companies.
I humbly - and I think intelligently - framed it as "I'd rather have (put names of CEO of exceptional companies here) managing my money than myself."
If one's not willing to liquidate/reallocate, then I think the next best thing is NOT to put incremental funds in a losing/risky investment.
If it's going to ultimately do well, then great, you recover and possibly make money. If not, you don't deepen the hole.
As for sex, you sound like Jack Lalanne.
--When asked about sex, LaLanne had a standard joke, saying that despite their advanced age, he and his wife still made love almost every night: "Almost on Monday, almost on Tuesday, almost on Wednesday..." (wikipedia)
